Ta aZl wiomit may onccm: Be it kil0Wn" that I, FRANK DREW W'INKLEY, a citizen of the United States, re-

siding at Madison, in the county of Madison and State of lVisconsin, have invented certain neW and useful Improvements in Car bnreters, of'which the following is a spcification. V

This invention relates in general to. carbureter s, and lias among its principal obj ects to Provide a carbureter which, When athydro-carbon engine, or, indeed, any liquid fuel engine is much more difiicult to start -than when the cylinders of the'engine are.

heatd to a certain degree Which aids vapori.

zation of' the liquid fuel; Thereiore, to ef fct the 1nore perfect vaporization of the liqnid fuel,' in accordanc'e with my presnt invention I in teip0se a removable heat-distribting member in the conductingpassage betsveen the carbnretenand the clinder or combustion chamber of' the engine at any.

suitable point, the heat-distributing member beirig.so arranged Within the passage that the oil or oil Vapors passing through the carburter into thcombustion bamber must necesSarily come in cohtactwith a heated wall or walls.of such heat-distributing member. The heatdistributhgmembex is"made readily removable from the'pxssag6 for the purpoSe of heat-ing the same by any suitable meai1S; or its heting may be partially or Wholly efiected when in place. A

The invention will be more specifically se forth and pointed out in the description embodied in this-spcification, and as shown in detail in the drawings in which Figure 1- is a longitudinal section of my innproved carbureter. Fig. 2 is a top plan view of Fig. 1. Fig. 3 is a side elevation view of a slightly modified form, with parts broken' away and other parts in section; and Fig. 4 is a view similar to Fig. 3, showin'g a further modification. V

Referring to thedrawings, and more particularly Figs. 1 and 2, the .carburcter herein shown consists of a shell or casing 5 having an air-passage 6 running therethrough, at one end of which is located a throttlevalve 7 mounted upon a valve-stem 8 extending. through one of the side walls of the casing and into the body. thereof. The casv ing is provided With an extension constitutingin partthe conductor leading from the carbureter to the combustion space of the engine, and in said conductor is formed a chamber 9', Which may be of any desired forn but is hrein shown as circular in cross section. The conducting passage 6. in'the carbureter opens into this chamberat one side thereof and leads from the opposite side of the chamber through the couplingnoz zle l0.

The carburecr is provided With the usual I feedpipe or spray-tube 11 leading from a fuel receptacle (not shown) and having a conical discharge end 12 opening into the air passage 6. Coperating with the conical e-nd 12 of the feed-pipe 11 is the needle valve 13, having a th1eaded connection with a boss 14 formed integral with the caSin said needle valve having the usual thu screw 15 for adjustmcnt thereof.

With the exception of the chamber 9, the parts 'of the carbureter and cohducting passage so far described are of an ordinary and well known type. The heat -'distribnting men'iber cope1ating with the ,chamber 9 consists in the several forms hereiri illus-"- trated of a rem0vable plug, the main body portion 16 of which is suitably cored to form connecting passages 17 and 18 on opposite sides of a central cors 19, said passager merging into each other at opposite ends of V the core, and. the merged ends on one side registering with the air passage-6, and on the other side with the couplingnozzle 10,

The plug is provided with a top portion 20 having a marginal flange 21 adapted to overlie and seal the upper edge 22 of the plug chamber 9 and effectivel close the latter. The heat-distribnting membcr or plug i's readily removable from the plug chamber by means of a handle 23, and any -suitable means may be provided, if desired, for se: curing the plug within the cliamber. The i1ozzle 10 leading from the plug chamber is shown threaded for connection vvith any form of pipe leading to the cylinder or combustion space of the engine.

When the foregoing parts are suitably attached to an angine from the chamber and suitably heated,

whereupofl it is then replaced in the cham-. ber, and when the carbreted charge is 'drawn through the carbureter and passes through the passages 17 and 18 it comes in sage 25 1 passage contact with the heated walls of the plug and thereby enters th combustion chamber in a thoroughly vaporizd state ready for instant ignition and combustion.

In Fig, 3 a'mcdifiediorm of heat-dis tributing member is shoWn wherein the opposite side walls of the body of the plug are slighfly eut away as shown at 24, and a pasis fornid in the cap portion 26 thereof, saidpassage 25 opening into the eut away portions 24 to form a connecting between the intake opening 27 *of the pl'ug joint 28 and the discharge opening 29. .This modified form of heat-distributing member is also provided .witha handle 30:

'- The heat-distributing member shoWn in F ig .4 is of substantiafly the same construction as the heat-distributing member shown in Fig. 3, with theeXception that its top is mg the plug formed with a 132151 31, into which a small amount of fuel of any character may be placed andignited for thepurpose of heatwithout making it necessary to remove the same fnoni the chamber, or for inc1easing or prolonging the heated condition of a previously heatedplug.

I am aWare that it is broadly old to preliminarily heat .a carbureted charge by exreceived haust products from the engine passing through a jacket surrounding the conductin pipe from the carbureter.

y invention is distinguished from such a device in that it is designated chiefly to facilitate the starting operation of the engine and to neutralize the baneful efiect of cold cylinder wa1ls upon the initial charges by the engine, the heat-distributing member of 'my invention being caused t0 absorb sufiicient heat -from some extraneous source t0 efiect the heating up of the initial charges when the engine is being started in operation.

invention is .limited to the particular form -of ca1bureter herein shown, 1101 to the particular forms of heat-discributing memberzs and described, I Claim:

"1. In combination with a carbureter foi gas-engines, a conductor leading from said crbureter to the combustion. space of the with a chamber interengine and formed passage, and a plug secting the conducting gas-engines, aconductor leading from said engine and formed with a chaniber intersecting the conducting passage. and a plug adapted to occupy said chamber and suit.- ably cored t0 constitute a section of said cohducting passage, said plg having a flange said chamber and being removable to heat the same, substantiilly as deScribed.

3.1n'combinatidn with a carburetei for gas-engines, a conductor leading from'said carbureter to the combustion space of-the engine and formed With a chamber intersecting tbe conducting passage, to occupy said chamber and to constitute a section of said conducting passage, and a handle on said plug whereby the same may be readily removed and replaced, substantially as described.
